Title: Process for producing flue gas gypsum in the course of the flue gas desulphurisation of power station boiler firings
Inventor: GEBHARD GEORG DR RER NAT
IPC: B01D53/50
Filed: 1987-08-20
Abstract: Process for producing flue gas gypsum in the course of the flue gas desulphurisation of power station boiler firings. The flue gas is treated in a scrubbing tower with a scrub water suspension containing lime or limestone and the sulphur dioxide thus scrubbed out is converted in the bottom of the scrubbing tower, with feeding in of atmospheric oxygen, by oxidation and by crystallisation into calcium sulphate dihydrate crystals. A circulating stream is drawn off from the bottom of the scrubbing tower and fed into the scrubbing tower via atomisation nozzles. A further crystal suspension stream is continuously drawn off from the bottom of the scrubbing tower and split by means of a cyclone separator into an underflow carrying crystal slurry and an overflow containing solid fines, with the underflow being dewatered, flue gas gypsum being drawn off and the resulting clear liquid being recirculated to the scrubbing tower and with the overflow containing solid fines likewise being recirculated to the scrubbing tower. At least 10% by weight of the solids contained in the crystal suspension have a particle diameter of less than 20  mu m and are carried along as solid fines in the overflow of the cyclone separator. A substream is separated from the overflow and replaced by a solids-free liquid. In this procedure, the particle size of the calcium sulphate dihydrate crystals drawn off is set by control of the amount of the substream, with, by means of throttling the amount of the substream, finer calcium sulphate dihydrate crystals and ...

Title: Arrangement for regulating the working depth of tractor-mounted appliances, especially ploughs, as a function of the pulling force
Inventor: SONNTAGBAUER ADOLF ING
IPC: A01B63/112
Filed: 1987-10-14
Abstract: In an arrangement for regulating the working depth of tractor-mounted appliances, especially ploughs, as a function of the pulling force, a controller (3) is provided for the actuator (1, 2) of the tractor lifting mechanism. The controller (3) is controlled, on the one hand, by a desired-value transmitter (5) and, on the other hand, by a pulling-force sensor (4) as an actual-value transmitter. At the same time, the difference between the higher values supplied by the desired-value transmitter (5), on the one hand, and the lower values supplied by the pulling-force sensor, on the other hand, is formed, and this difference is compared with a preselectable limit value. When the difference exceeds this limit value and a change in a second operating variable above a predeterminable value occurs simultaneously, a signal is fed to the actuator (1, 2), bypassing the controller (3), with the effect of raising the mounted appliance. In order, at all events, to prevent the tractor from sinking in, the rotational speed of the tractor driving wheels is measured continuously as a second operating variable by means of a sensor (10), and the signal transmission to the actuator (1, 2) is made dependent on the exceeding of the predetermined rotational-speed value. <IMAGE>

Title: Switching arrangement for actuating a switch which is mounted on the wheel of a motor vehicle and is used to monitor the inside pressure of tyres
Inventor: WEIBLER WOLFGANG DR
IPC: B60C23/20
Filed: 1988-07-09
Abstract: The invention relates to a switching arrangement for actuating an electronic switch which is on the side of the wheel, is contained in an oscillating circuit and, in the event of a critical air pressure not being achieved in the inside of the tyre, is opened by a pressure measuring bridge with piezoresistive resistors via an amplifier and a comparator. The switching threshold of the said comparator is affected by a voltage distributor with temperature-dependent resistors in such a way that the air pressure switching point follows the temperature to achieve an ideal gas equation. As the oscillating circuit on the side of the wheel is inductively coupled to a pulse generator or a vibration generator and to an evaluation device on the chassis, the said evaluation device is able to detect the closing and/or opening position of the electronic switch at any time.

Inventor: BITTLMAYER HUGO
IPC: B21F27/20
Filed: 1988-08-23
Abstract: The invention relates to a method for reinforcing concrete slabs, a device for carrying out the method as well as lattice girders (1) which can be manufactured by this means. The reinforcing structure made from lattice girders, which is designed in conventional manner to meet static requirements, is composed of individual wire rods of suitable diameter and suitable length. In particular, the diagonal rods (5, 6), which are firmly connected, in particular welded, via bases (7, 8) to the bottom booms (3, 4) and via vertices (9) to the top boom (2), can be produced individually in this way, varying over the length of the lattice girder (1). In particular, they can be produced in accordance with static requirements with a different base distance (a3) and/or different shape and/or different bending radius and/or different diameter. Furthermore, the neighbouring bases of neighbouring diagonal rods (5, 6) may be at different distances (a2) from one another. In this way, a cutting-free production of lattice girders (1), which meets static requirements in each case without fail, is possible. It is ensured that the terminal bases (7) of the terminal diagonal rods (5) are firmly connected to the respective bottom boom (4) and, if appropriate, are at a safe distance (a1) from the end of the bottom boom. In order to produce the diagonal rods (5, 6) and the booms (2 to 4), appropriate wire rods can be taken from a stock of wire coil, straightened and cut into suitable lengths. Positioning and/or sorting is expedient. The method makes possible considerable rationalisation in the manufacture of concrete slabs. Furthermore, a considerably saving of steel can be achieved. <IMAGE>

Title: Warning device
Inventor: VOELCKERS JUERGEN
IPC: B60T8/48
Filed: 1989-01-18
Abstract: In a known warning device for indicating the risk of the braked wheels blocking and/or the driven wheels of a motor vehicle spinning, the rpm of the wheels and the acceleration or deceleration of the vehicle is detected by means of sensors, the instantaneous wheel slip is calculated constantly from the detected sensor signals and the wheel slip is formed as a function of the vehicle acceleration. This function is compared with slip characteristic curves, stored in memory units, for particularly typical road surface states and conclusions as to the degree of utilisation of the prevailing coefficient of friction of the road surface are made from the comparison. The new warning device is intended to provide comparable informative capabilities and reliability with a very much lower outlay on circuit technology. The new warning device contains an electronic circuit unit, preferably a microprocessor, which continuously forms the rpm difference between the rpms of the rear wheels and of the front wheels from the sensor signals fed to it and outputs an output signal for the actuation of a signal unit when the detected difference in rpm exceeds a predetermined difference value, preferably in the order of magnitude of approximately 10%. <IMAGE>
